염화칼슘 2수화물 C화학적 특성, 용도, 생산
화학적 성질
Calcium chloride is a colorless to off-white crystalline solid which is deliquescent (absorb water). When heated, crystals lose water @ 100C.용도
Calcium chloride dihydrate is widely used as an ingredient in ceramic slipware, cosmetic and food items. It acts as a pH buffer in swimming pool water. It provides inhibition of swelling clays in the water phase of invert emulsion drilling fluids. It is employed in the oil industry to increase the density of solids-free brines. It is used as a flux in the Davy process for the manufacture of sodium through the electrolysis of molten sodium chloride. It finds an important application as an additive in plastics, fire extinguishers, blast furnaces and in wastewater treatment as a drainage aid.정의
ChEBI: A hydrate that is the dihydrate form of calcium chloride.Biological Functions
Calcium chloride is a commonly used reagent in biochemistry. Calcium plays important roles in many biological processes, including signal transduction, muscle contraction, and maintenance of cell membrane and cell wall stability.Extensive reviews of the experimental measurement of biological calcium have been published.Calcium chloride is used in the preparation and transformation of competent E. coli and in the transfection of eukaryotic cells with either plasmid DNA or high molecular weight genomic DNA.The CaCl2-mediated electroporation of E. coli with the plasmid DNA pBR322 has been studied.A protocol for the concentration of virus vectors that uses CaCl2 has been published.
CaCl2 has been used in the stabilization and twodimensional crystallization of the NADH-ubiquinone oxidoreductase (complex I) from Escherichia coli. The crystallization of porcine pancreatic elastase in the presence of CaCl2 in the presence of sodium citrate reveals binding of calcium in the metal binding site of the protein.The effect of CaCl2 on the total fluorescence in the polymerication of the tubulin-like FtsZ division protein of Escherichia coli has been studied by a multiwell fluorescent assay.
일반 설명
ACS Reagent Grade.잠재적 노출
Calcium chloride is used as road salt for melting snow, a drying agent in desiccators, for dehydrating organic liquids and gases, in refrigeration brines and antifreeze, as a dust-proofing agent, food additives, concrete hardening accelerator, and others. May react with strong oxidizers.운송 방법
There are no label or maximum shipping quantity requirements set by DOT.Purification Methods
Crystallise it from ethanol. It is hygroscopic. It loses H2O at 200o so it can be dried at high temperatures to dehydrate it. The hexahydrate [7774-34-7] has m 30o and d 1.67.비 호환성
The solution in water is a weak base. Reacts with zinc in presence of moisture, forming highlyflammable hydrogen gas. Dissolves violently in water with generation of much heat. Incompatible with water, bromine trifluoride; 2-furan, percarboxylic acid. May attack some building materials and metals in the presence of moisture.염화칼슘 2수화물 준비 용품 및 원자재
